setup 模块

setup 模块用于收集远程主机的一些基本信息。常用参数 filter，使用 setup 常搜集的信息，这些 facts 信息可以直接以变量的形式使用，但是如果主机较多，会影响执行速度，可以使用 gather_facts: no 来禁止 Ansible 收集 facts 信息

filter=
        ansible_all_ipv4_addresses：             仅显示ipv4的信息。
        ansible_devices：                        仅显示磁盘设备信息。
        ansible_distribution：                   显示是什么系统，例：centos,suse等。
        ansible_distribution_major_version：     显示是系统主版本。
        ansible_distribution_version：           仅显示系统版本。
        ansible_machine：                        显示系统类型，例：32位，还是64位。
        ansible_eth0：                           仅显示eth0的信息。
        ansible_hostname：                       仅显示主机名。
        ansible_kernel：                         仅显示内核版本。
        ansible_lvm：                            显示lvm相关信息。
        ansible_memtotal_mb：                    显示系统总内存。
        ansible_memfree_mb：                     显示可用系统内存。
        ansible_memory_mb：                      详细显示内存情况。
        ansible_swaptotal_mb：                   显示总的swap内存。
        ansible_swapfree_mb：                    显示swap内存的可用内存。
        ansible_mounts：                         显示系统磁盘挂载情况。
        ansible_processor：                      显示cpu个数(具体显示每个cpu的型号)。
        ansible_processor_vcpus：                显示cpu个数(只显示总的个数)。
  • 搜集主机的所有系统信息
ansible 192.168.169.161 -m setup
192.168.169.161 | SUCCESS => {
    "ansible_facts": {
        "ansible_all_ipv4_addresses": [
            "192.168.169.161"
        ], 
        "ansible_all_ipv6_addresses": [
            "fe80::7d00:28cc:f94f:a06a", 
            "fe80::ad67:cf07:7fc:c440"
        ], 
        "ansible_apparmor": {
            "status": "disabled"
        }, 
		........
  • 搜集系统信息并保存在指定目录，默认自动创建文件名，即为主机 ip 地址
[root@master ~]# ansible dong -m setup --tree /root/masterInfo
[root@master ~]# cd masterInfo/
[root@master masterInfo]# ls
192.168.169.161  192.168.169.162
或者直接使用
[root@master ~]# ansible dong -m setup > /root/masterInfo.txt
  • 搜集内存相关信息
[root@master ~]# ansible 192.168.169.161 -m setup -a "filter=ansible_*_mb"
192.168.169.161 | SUCCESS => {
    "ansible_facts": {
        "ansible_memfree_mb": 694, 
        "ansible_memory_mb": {
            "nocache": {
                "free": 801, 
                "used": 175
            }, 
            "real": {
                "free": 694, 
                "total": 976, 
                "used": 282
            }, 
            "swap": {
                "cached": 0, 
                "free": 1023, 
                "total": 1023, 
                "used": 0
            }
        }, 
        "ansible_memtotal_mb": 976, 
        "ansible_swapfree_mb": 1023, 
        "ansible_swaptotal_mb": 1023, 
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false
}
  • 查看主机内核
[root@master ~]# ansible dong -m setup -a "filter=ansible_kernel"
192.168.169.162 | SUCCESS => {
    "ansible_facts": {
        "ansible_kernel": "3.10.0-693.el7.x86_64", 
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false
}
192.168.169.161 | SUCCESS => {
    "ansible_facts": {
        "ansible_kernel": "3.10.0-693.el7.x86_64", 
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false
}
  • 搜集网卡信息
[root@master ~]# ansible 192.168.169.161 -m setup -a 'filter=ansible_ens*'
192.168.169.161 | SUCCESS => {
